Mapping

The Department of Public Health (DPH) Division of HIV and STD Programs (DHSP) utilizes mapping to inform distribution of resources for HIV and sexually transmitted disease (STD) prevention and treatment in Los Angeles County. Geographic Information Systems (GIS) is a computer system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. DHSP has been using this important tool since 2004 to develop maps to identify geographic areas with higher HIV and STD burden facilitating improved distribution of scarce resources to the communities and people most in need. Data for the GIS is captured from various sources including DHSP's HIV Surveillance data, STD Surveillance data, HIV Testing Services data, HIV Care Services Utilization data, and the Los Angeles Coordinated HIV Needs Assessment (LACHNA). The maps created from the captured data in GIS is used in conjunction with other data sources to not only aid in resource distribution, but also to evaluate the effectiveness of HIV and STD prevention and care services county-wide.

DHSP Mapping Project - 2010-2014 HIV & STD Burden by Health District

The latest mapping endeavor, 2010-2014 HIV & STD Burden by Health District, ranks geographical areas in order of highest to lowest HIV and STD burden throughout LAC to more efficiently distribute resources to communities in most need. Geographic areas (health districts) are ranked by several important driving factors for the geographic burden of HIV and STDs: number of infections, number of people infected, the population size, geographic size, and results from the hot spot analyses*.

The 2010-2014 HIV & STD Burden by Health District plays a critical role in informing and updating DHSP's continuing efforts to reduce new HIV and STD incidents and account for all reported cases of HIV and STDs in the City of Long Beach, City of Pasadena, and throughout LAC. Its primary purpose is to support geographic prioritization of DHSP resources by updating and building upon the GIS syndemic cluster maps produced by DHSP in 2009. Additionally, the new mapping strategy shares regularly collected HIV and STD surveillance data in a way that highlights the interrelationships between HIV, syphilis, gonorrhea and chlamydia. Rather than looking at each disease in isolation, the mapping of HIV and STD Burden by Health District allows for each HIV/STD to be viewed in the context of a person's other diseases and from several other vantage points, including:

1. Aggregated to health districts for detail on HIV and STD infected populations (i.e., health district profiles);

2. Aggregated to census tracts for LAC disease-specific maps showing the differences of disease spread relative to risk fo HIV infection or transmission (i.e., bivariate maps); and

3. Aggregated to census tracts and analyzed using hot spot analysis to map where we have unexpectedly higher numbers of incidents (i.e., HIV/STD Highly Impacted Areas maps).

By building upon the 2009 syndemic cluster mapping and by sharing data in these various ways, DHSP and agencies critical to reducing new HIV and STD infections will have the information needed to create truly synergistic prevention and treatment programs for both HIV and STDs.
